SPECIFICATION forming part of Letters Patent No. 365,859, dated July 5,1887.

Application filed January 21,1887. Serial No. 225,003. (No model.)

To aZZ whom it may concern:

Be it known that 1, CHARLES B. PORTER, a citizen of the United States,residing at Bay City, in the county of Bay and State of Michigan, haveinvented certain new and useful Improvements in Dental Brackets; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make'and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in dental brackets, and isdesigned to hold the tools and accessories of dental work in a positionto be easily obtainable when a patient is being operated upon.

The invention consists in the general construction, arrangement, andcombination of the parts of the device, as I hereinafter more fullydescribe and claim; and the objects of the invention are to form aconvenient and handy device for holding the tools to be used inoperating in dentistry or surgery in a manner operation.

that whenever aset of instruments are needed to be used in one portionof the operation they can be swung into position and the set used for aformer portion of the operation can be swungback and away from theoperator, and when not in use that can be folded to occupy but a smallspace and can at once be extended into position again without extratrouble of handling and placing the different sets of dental or otherinstruments at each stage of the My improved deviceisillustrated intheaccompanying drawings, in which- Figure 1 is aside view ofmyimproveddental bracket secured to the wall and in an extended position. Fig. 2is a View of the same in a closed position. Fig. 3 is a top view ofFig.1, showing the parts in different positions. Fig. 4 is a verticalsectional detail of a detached portion carrying friction-rollers,hereinafter described. Fig. 5 is a horizontal section of the same.

a represents a frame, consisting of the vertical piece a, hinged to thewall of the office in a convenient position andprovided with extendedarmsb, to the outer end of which is secured the vertical standard Z).

c are short upper and lower arms, having an opening on their inner ends,through which is passed the standard b,- and c is a vertical standardsecured to the outer ends of the arms 0,- and is of a proper length tohold the arms just beneath and above the connection of the standard bwith the arms b,and allow the arms and standard 0 to swing upon thestandard b to any position, and the connection of the upper arm 0 isprovided with a clamping-screw, d, with which to secure the arms andstandard 0 in any desired position.

d is a smaller frame, consisting of the vertical sleeve 6, passed uponthe standard 0, and

with its upper and lower ends provided with the upper and lower extendedarms, 6', to the outer end of which is secured the vertical standard f.This standard f extends above the upper arm for a short distance, and ispro: vided witha revolving table, f, andbelow the table is pivotallyconnected to the standard f an arm, 9, which extends to a part beyondthe table f, and is provided with'a holder, 9, within which is placed aglass for water or a spirit-lamp, and may be swung to any conven ientposition around the tablef.

h is a horizontal arm, which is provided on one end with a short sleeve,'5, through which is passed the standard f, and to the outer end of thearm is pivoted a revolving table, h. This arm is provided with one ormore pivoted joints, as desired, which allows the table h to be placedin any desired position from the patient; and the connecting sleeve imaybe raised or lowered upon the standard f, the weight of the extendedarm and table It holding the piece i in any desired position on thestandard. A collar, .9, is placed upon the standard 6, below the frameit, and is held in a desired position by a clampingscrew, it, and theframe resting upon this col lar may then be swung to any position without moving vertically. Below the frame at is secured by a short sleeve,Z, one end of the swinging arm 2', and upon the central portion of thisarm is a cotton holder or cup, j, having a lid, j, provided with acentral opening, through which the cotton protrudes in a manner to beeasily caught by the fingers or with an instrument; and to the outer endof the arm z" is secured a waste-cotton holder or cup, 7:, provided withan opening having upon its edge the teethk, upon which the cotton usedin an operation may be removed from the instrument by catching thecotton upon the teeth is and withdrawing the instrumenttherefrom,and thecotton then drops within the cup The sleeve Z allows the arm to beraised to any desired position upon the standard 0. The sleeve beingshort, it binds against the standard by the weight of the arm and cups,which prevents the sleeve from sliding downward, so that a free swingingmovement and also a vertical movement are obtained for the arm andcotton-holders, which remain in out extra fastening. I

Z is a connecting-piece placed upon the lower portion of the standardb,and is provided with a clamping-screw, m, and'a portion, w, of thispiece is pivoted to the lower end of one of the diagonal pieces at of alazy-tongs or zigzag arm, 0. I

o is a connecting-piece sliding upon the standard I), and is providedwith the rollersp and p in front and rear of and bearing against thestandard, as shown in detail in Figs. 4and 5, and to a portion extendingin front of the roller 19 is pivoted one end of the piece a of thezigzag arm 0, By means of theserollers p and p a free and easy slidingmovement of the piece 0' upon the standard is obtained, so

position withthat when the arm 0 is extended or receded the piece 0 ismoved vertically by the diagonal piece 1LT without catching or bindingagainst the standard.

The arm 0 mayconsist of any number of the pieces a and n pivotedtogether, and to the outer end of the pieces are pivoted the pieces gand g, and a vertical standard, 1', is passed through the upper piece,q, and into the lower piece, q, and when the arm is being extended orreceded the piece q slidesupon the standard a, and is providedwith-rollers p and 12, if desired, in the same manner as the piece 0,the movement and operation of the pieces 0 and q being the same.

Upon the standard r,and between the pieces q and q, is placed ashortsleeve, t, having a horizontal arm, 1*, extending from one side, and tothe outer end of this arm is pivotally secured a table, 8, for holdingdental instruments and appurtenances.

The zigzag arm 0 may be moved to any desired height and secured by acollar, t, and clamping-screw u, and may then be swung to any positionhorizontally and there secured by the clampingscrew m.

The table 8 may be raised, if desired, by sliding the sleeve 1? upwardupon the standard to any desired position, where it will remain, theweight of the table binding the short sleeve t upon the standard, and itmay be then swung in either direction.

The zigzag arm allows the table 8 to be placed in any position to orfrom the standard, or to be folded within the frame a, as shown in Fig.2.

Upon the upper portion of the standard I) is placed a thread-holder, o,in which are a number of pins supporting spools of thread, and a shortblade, 11, forms a thread-cutter and is secured to the holder in aconvenient posltion, so that thread of various sizes is always at handand ready for the operator.

It is not necessary to attach all of the portions of this device to theframe a, as some classes of work do not require so many devices orchanges; and the frame may be used without the zigzag arm and supply thewants of very many operators, and other portions not needed may be leftoff, if desired.

When the device is operated without the arm c,the frame d is supporteddirectly by the standard b, and the standard 0, not then required, isremoved with the arms 0. Vhen any portion ofthe device is not needed foruse, it may be swung to the position shown 1n Fig. 2 and only theportion desired swung outward. This allows the instruments for oneoperation-sueh as for filling-to be placed upon one of the tables andswung into position for use, and the instruments for other operationsare swung back within the frame a, so that this arrangement allows theinstruments to be always ready at hand and out of the way when not inuse; and when no portion of the bracket is required for use the partsare closed in the manner shown in Fig. 2, and the frame dis then swungagainst the wall and occupies but a very small space.

I do not confine my invention entirely to placing the attachments in theposition shown. as some operators may require the arms and tables indifferent positions, and the parts would operate in a similar manner ifplaced in different positions; but

WVhat I claim as'my invention is- 1. The combination, in a dentalbracket, of the frame a, hinged by one end to the rigid support, with avertical standard, 0', hinged to the outer end of the frame a by theshort arms a, a sleeve, e, sliding upon the standard a and provided oneach end with horizontallyextending arms e, a vertical standard, f, secured to the outer ends of the arms, and with its upper end extendingabove the arms, and a table, f, upon the upper end of the standard,substantially as herein set forth.
